To all whom it may y Be it known 'that I, Rosana' G. C. Boa, residentofthe borough ,of4 Manhattan, Y York, in'the county of `New York andState of New, York, have invented certain new 'and useful Improvementsin Calculating of whichthe following is a speci-v Machines, cation.-

My' invention relates tocalculating rma@ chilies and especially tocombined typewrit-I.

iniand calculating 'niiivchinesiV y invention has for its principalobject to rovide improved means for securing in ad]usted position a.partgof a calculating machine and more specifically to provide "improvedmeans for securing to its truck the adjustable totalizer ofl a combinedtypewriting and adding machine. y

To the above and other ends my inven tion consists in Vcertain featuresof construction and combinations and arran ments of arts, all of whichwill be fu y set forth erein and particularly pointed out in the claims.

In the present instance I have shown vmy invention applied to aReminlgtomwah 'inffront of sai'dtruck.

` 10 upper dove-tail Hangs 17 the tension of the :Kring holding thetotalizer snug e truck. The right-hand arm 23 1s shaped into a tooth 29that enters between two of the teeth 21 and locks the totalizer inplace.

151' By operating the above mentioned handle the arms 23 and 24 can beraised and the totalizer can be slid to an desired letter space positionlongitudin y of the truck -and locked there byv said tooth 29.

The coupling device 15, 16 takes hold of a lug 26 which rojectsdownwardfrom the rear' corner o the ri llt-hand frame plate. The corres ndingg1g 27 (Fig. 7) of theleft-hand e plate does not ex- 25 tend downwardfar enough to be engaged by this device.

The spring 25 holds the totalizer snugly in place but the locking tooth29 is at the per part of the totahzer and the lug 26 the .totalizer isat the lower part thereof. Under these conditions it is deemedpreferable to lock the totalizer positively to the truck ait a pointcloser to thepoint of engagement of the hookfl than has hereto fore beendone. This is found especially desirable where the 'machine is operated'vigorously and especially in that orm of the machneshown in the patentto Wahl No. 1,349,024, dared August 1o, 1920` and in which the crossfooting truck is made longer so as to accommodate two totalizers of one.Inthis machine the weight that is controlledl by the couplers 15, 16 isconsiderable, 4and better results are obtained if the vertical totalizeris' positively locked to the truc'kat or near the lug 26; and this 1saccomplished by 1n present invention.

The lower part of e truck 11 is made of a cross section somewhatdi'erent from that to d f d1 atente above an a orwar y acm groove 2) iscutin said truck agd in said 1go there are movably mounted a. locking ar31 and avshift.' bar 32, the former overlying e locking bar 31 ,has aseries of teeth 33l rejecting from itsforward edge, y sald teethpreferably more on leasv beveled as shown, and the notches between thembein of a width to take hold of the 0 lug 26 of "e totalizen= This bar31 is capable o-f slid' forward to the position shown 1n Fig. 3 w ereits teeth are in locking engagement with said lu 26 and rearward to theposition shown in 4 where said teeth 35 arefreeofsaid'luganthetotalizercan,

alon the truck. At intervals in its length the ar`31 has small roundlugs or pins 34 projecting downward therefrom into cam slots 35 in theshifting bar 32. The number of these pins would depend on the length ofthe bars which depend on the length of the truck, which in turn co ndsto the length or'width of the typewriter carriage. These parts aremanufactured of various lengths according to the width of the parelrthat it is desired to use in thetypewriter. e pins or lugs 34 can bevmade in any suitable way as for example, by riveting them in the bars.Inthe present instance they are marie by unchin a depression 36 (Fig.10) in the ar 31, t is bein done by means of a die or unch when sai bar31 is lying on another ie havin a round hole directly under said punch.aid unch is forced partway through the bar, t us forcingr part of themetal down into'. said roun ole and thus producing a lug or pin. Thishowever vis merely a shop expedient and as far as my invention isconcerned the lug 34 can be made in any suitable way.`

' Each of the slots35 hasits ends'l mg parallel with the l h 4of the shiing bar 32 Aand its mid e. art inclined so r that when said shifting bar1s pushed toward the left as shown in Fig. 3 the pin 34 is -forcedtoward the front of the machine and when said shifting bar is pushedtoward the right as shown in Fig. V4 said pin is. cammed to the rear;and in each plosition the pin 34 lies in a parallel or d we portion ofthe slot 35, so that bar 31 is .positively held in its lockin or in itsreleasingposition.

The Wa machine as heretofore constructed comprises a rackybar 37,.th.eteeth of which are en ged"by a certain dog shown in the Wa lpatentsrabove referred to, to lock the truck ainst longitudinal motionduring the operation of the totalizer, this rack being secured to thefront face of thetruck b means of screws 38 (Fig.- 1). I utilize sai bar37 to close the lower part of the groove 30 in front of the shift- 'mgbar 32 which shifting bar ismade of a width equal to the depth of saidgroove so Vthat whereas'this bar can slide lengthwise right and left, itcannot move frontend back, being restrained between the rack bar Theseplates 40 preventlongitudi nal motion of the locking bar 31 butallow itto move front andback. This .it does equally at all parts of its lengthon account of thel pins 34 and slots 35 being distributed along thebars. 1

micajif desired.

to form a handle or finger piece 45. L Each of the plates 40 has a slot46 cut therein so as to accommodate the part 43 but terminating at therear just back of said prt 43 so that the shoulder '44'cannot pass yondthe end of the truck. The parts are so constructed 'and pushed or pulledto the right or left a distance a proximating the length of the slot 35bu no farther. When said bar isv in its extreme right-hand position Aasshown' in FigsA and 12 the lockmg bar 31T is pulled to' unlockingpositionand when said shifting bar is moved in its extremeleft-handposition as shown in Fi -1, 3 and 11 then-the 'locking bar 31 is inlocking' osition.

er t0 retain the shifting bar 32 in its adjusted positions any suitabledetent ca n be employed.- As'here shown said bar end two depressions 47into 'which a-ball 48' is adapted to ressed by a com ression spring 50.Said all occupiesy a suitable hole Adrilled upward of the truck ll'and.the

spring 50 is seateda in a bracket51 w ch is secured by a screw 52to theunder sideof thetruck 11. The construction iSSllch that' the bar 32 canbe of impositions' t the `other 48 will prevent it from accidentallyjarring out of place. Since the ends of the slots 35 are parallel 'tothe length of the truck the pins 34 lareposit'ively -held in theirforward or backV positions.

It will Abeseen that any desired number of vertical totalizers can `bemounted' on the truck and adjustedto'their, respective positions in thesame man ner as heretofore and that then the bar 32' can be shifted toits leftfha'nd ,position `causing the locking bar and to take-a posi' 26of. all of said tota1iz'ers,'thus positive against 'right or left-handisplacement at a polnt quite close to that .at which the couplm device15, 16 exerts a. right or *lefthan force on said totalizers; In theW'ahl machine, the vertical total izers 14 are sometimes. replaced by socalled dummies, these being frameworks similar to the frame ofa:totalizer but containing no computingmechanism. vFor the purposesconsider these dummies to be the same as totalzers.v Y The-locking bar31 and Vits adjuncts can be used alone and the Y pper lrack 20 can beproportioned as to allow .6 I
